From bed7118988ef48063c72f67cc2701c72663b3870 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Fri, 11 Jul 2014 08:15:32 +0900 Subject: ARM: EXYNOS: Register cpuidle device only on exynos4210 and 5250 Currently, the exynos cpuidle driver works correctly only on exynos4210 and 5250. Trying to use it with just one CPU online on any other exynos SoCs will lead to system failure, due to unsupported AFTR mode on other SoCs. This patch fixes the problem by registering the driver only on supported SoCs and letting others simply use default WFI mode until support for them is added.
